Hello, I am trying to build code of a recently graduated student, who is now unavailable to us (read: ignores us). When running scons in the appropriate directory, a lot gets build, until I get the following error: /usr/include/boost/python/object/make_holder.hpp:81: error: 'allocate' is not a member of 'boost::python::objects::value_holder<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, State> >' /usr/include/boost/python/object/make_holder.hpp:83: error: no matching function for call to 'boost::python::objects::value_holder<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, State> >::value_holder(int*&)' /usr/include/boost/python/object/value_holder.hpp:44: note: candidates are: boost::python::objects::value_holder<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, State> >::value_holder() /usr/include/boost/python/object/value_holder.hpp:44: note: boost::python::objects::value_holder<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, State> >::value_holder(const boost::python::objects::value_holder<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, State> >&) scons: *** [trackerbase/trackerbasewrapper.os] Error 1 scons: building terminated because of errors. This does not seem to be an error in his own code, rather an error in the boost.python code? This is the first time I am using boost, and, as usual, I need to get this program working yesterday. My machine is a recently installed Ubuntu Feisty (hence the need for re-compilation). I am using the latest version of Boost (boost_1_34_1) and python 2.5.1 Any help would be appreciated.
